(Cl. 49-8l) The invention is a method of and apparatus for splinter the glass surfaces as they come into conreclaiming the materials of the so-called nontact, pass through between the breaking shatterable glasses, The b calling-gears are mounted on shafts It has, among its objects, to provide for the reii which run in adjustable bearings 6, and are pro- 5 claiming of the glass and binder used in making vided with a suitable trainer gearing l and source 5 non-shatterable glass, which includes the glass or motor 2. itself and the celluloid or other binder used; to A table is mounted on the frame and guides have a machine that will break up the glass and the glass to be r claimed to the breaking-gears, segregate it from the binder material; to have an the latter being spaced to permit the binder I0 arrangement for adjusting the machine for the to pass freely through while the glass H is crushed various classes of work and provide for more by the diamond pyramidical points. A suction adaptable operation; to have an arrangement for funnel i2 is placed to catch and suck in the dust processing the materials after they have passed from the machine. As the glass is crushed by through the primary stage and thereby make the the breaking gears it flows through a channel segregation more complete; and other objects that box it into bin where it collects for dis- 15 will become apparent as the invention is more posal.
